Why is it difficult to place components freely in my GUI form?

I thought for a while and I realised building GUI in IntelliJ UI builder is really pain in the head. Hard coding the layouts and other components is way better (even though time consuming) than using the drag-and-drop whatever thing. When I just want to create a simple form and it is making my life so difficult. Can't you guys please just add a free layout manager or something so I can just put my thing exactly where I want without any Layout Manager Sheriff ordering me?

But I think IntelliJ will get there very soon.... like 5000 years to come .......
